WELSBACHA y.OR OTHER INCANDESCENT BURNER.

SPECIFICATION forming part f Letters Patent N0. 699,251, dttd May 6, 1902.

' Application filed November 14, 1901. Serial No. 82,175. (N0 111011610 T0 all whom. t ntay concern:

Be it known that I, VICTOR H. SLINAGK, a citizen of the United States, residing at Philadelphia, in the Ycounty .of Philadelphia and State of Pennsylvania, have invented a new and useful Improvementin Welsbaeh or other Incandescent Burners, of which the following is a specication. In the class of burners referred to provision vconstructions are, however, all more or less defective, chiefly because the parts being nec-v essarily threaded the thread soon becomes stripped or worn, with the result that the needle-valve becomes wasteful of gas.

It is the principal object of my invention to guard against this loss or waste.

f Further objects are to simplify the general construction of the burner, to add. to its attractiveness, and to make the burner more efficient as a Whole. i

The nature, characteristic features, and scope of the invention Willbe more clearly understood by reference to the following description, taken in connection with the accompanying drawings, forming a part hereof, in Which- Figure l is a side elevational view of the burner constructed in accordance with. my invention, illustrating a simple mantle-support holder. Fig. 2 is a central vertical sectional view of the same. on line 3 3 of Fig. 2, and Fig. 4. is a viewsimilar to Fig. 1 with a gallery applied.

In the illustration herein given use is made of a support or yoke a, served with annular openings'at top and bottom for the reception of the various parts. the yoke constitutes the lower part of a Bunsen mixing-tube and has apertures b for the ingress of air. c is a thimble or member, one function of which is to connect said tube with the gas-valve. An apertured sleeve or air- `shutter LZ is revolubly mounted between the Fig. 3 is a section The base or bottom of member c and the yoke and coperates with the' apertures b to admit more or less air to the burner in a manner well understood. The member c is threaded to fit a correspondinglythreaded part of the Bunsen tube and has a central orifice e, which constitutes the seat for a needle-valve j, the shank of which extends in the direction of the burner. The yoke a. is provided with a boss or member g, which is exteriorly threaded and on its inside constitutes a shoulder, the purpose of which will be presently explained. The member g receives a milled collar h, by which the needle-valve is adj usted and which has the spider i for supporting the shank of said valve. The adj ustable parts are shown as .being provided with screw-threads; butit is manifest that other common means of adjustment might be resorted to if expedient or desirable. The casingj or upper member of the Bunsen mixingtube is shown as being somewhat enlarged at its base and tted to turn with the member g, but capable of ready detachable connection therewith, as well as from the burner-head lo, into which it extends. Provision is made for removing the burner-head 'ing a set-screw. As shown in Fig. 2, the ring is secured in position by mounting it on the' top of the yoke'or support and screwing the burner-head down upon it. This is an inexpensive way of providing a holder for the mantle-supporti but the` ordinary gallerysupport m (shown in Fig. 4) may be employed by simply 'sleeving it over the' burner-head. The jet or stream of gas when it reaches the needle -valve is split up by the latter and caused to impinge on the shoulder formed by the inner wall of the boss or member tr/,vvhich in turn still further acts to break the force of thel jet, besides tending to perfect the mixture of gas and air by establishing counter opposing currents. This is important, for the pressure of gas in mains often iiuctuates, particularly, as before stated, in the case of natural gas, to the detriment of the life'f the'mantle. .Y

It will be obvious to those skilled in the art to which the invention appertains that modiications may bermade in details Without departing from the spirit and scope of the same. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove set forth, and illustrated in the accompanying drawings; but,

Having described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In an incandescent burner, the combination of a Bunsen mixing-tube having an internal annular shoulder, a member adapted for communication with a gas-supply connection and with said Bunsen mixing-tube and having a valve-seat that projects into the Bunsen mixing-tube, and a needle-valve superimposed in said BunsenmiXing-tube and adapted to said valve-seat and acting when open to direct the gas-jet against said shoulder, substantially as described.

2. In an incandescent burner, the combination of a Bunsen mixing-tube having an internal annular shoulder, a tubular member detachably fitted in said Bunsen mixing-tube arranged for attachment to a gas-supply connection and having a valve-seat, and a needle-valve superimposed in said Bunsen mixing-tube adapted to said valve-seat, and acting when open to direct the gas-jet against said shoulder, substantially as described.

3. In an incandescent burner, the combination of a Bunsen mixing-tube having au internal annular shoulder, a member detachably fitted in said Bunsen mixing-tube arranged for communication with a gas-supply connection and with said Bunsen mixingtube and having a valve-seat, a needle-valve superimposed in said Bunsen mixing-tube adapted to said valve-seat and acting when open to divert the. gas-jet against said shoulder, and means for adjusting the supply of air, substantially as described.

4. In an incandescent burner, a Bunsen mixing-tube having its inner Wall provided with an annular shoulder, and means for regulating the admission of gas to said tube and causing it to impinge on said shoulder, substantially as described.

5. In an incandescent burner, the combination of a Buusen mixing-tube having an internal annular shoulder, a support the base of which constitutes the lower part of said Bunsen mixing-tube, a thimble threaded for attachment to said base and with a gas-supply connection and` provided with a valveseat that projects into the Bunsen mixingtube, a needle-valve superimposed in said Bunseu mixing-tube adapted to said valvea seat and acting when open to divert the gascurrent against said shoulder, and means revolubly mounted with reference to the support for controlling the admission of air to the Bunsen mixing-tube, substantially as described.

In testimony whereof I have hereunto signed my name in the presence of two subscribing witnesses. Y v
